  • the header 200 also includes a counter knife 302 (e.g., a counter blade), which may facilitate operation of the chopper 300 in cutting the MOG.
  • the counter knife 302 may support the MOG being moved by the feed rollers 260 and provide resistance to enable the chopper 300 to cut the MOG more easily.
  • the chopper 300 may cut the MOG against the counter knife 302 such that each of the chopper 300 and the counter knife 302 imparts a force against the MOG to cut the MOG.
  • the counter knife 302 may improve operation of the chopper 300.
  • the counter knife 302 may be coupled to the row unit 204, such as to a support 303, and may extend toward a front end 304 (e.g., an upstream end, a tip) of the header 200, such as generally in the longitudinal axis 142. Thus, a portion of the counter knife 302 may overlap with the chopper 300 during rotation of the chopper 300 to enable the counter knife 302 to contact and support the MOG being cut by the chopper 300.
  • the position of the counter knife 302 may be adjustable.
  • the counter knife 302 may be coupled to the support 303 at a pivot 305, and the counter knife 302 be rotated about the vertical axis 144 at the pivot 305 to adjust a direction of extension of the counter knife 302.
  • Such movement of the counter knife 302 may adjust an overlap between the counter knife 302 and the chopper 300 during rotation of the chopper 300.
  • the counter knife 302 may be moved to adjust a force imparted by the counter knife 302 onto the MOG, to adjust a location (e.g., along a length of the feed rollers 260, along a length of the MOG) where the counter knife 302 engages the MOG, or to otherwise adjust how the MOG is cut via the chopper 300. Movement of the counter knife 302 to increase extension toward the front end 304 (e.g., to extend more in the longitudinal direction 142) may enable the chopper 300 to cut the MOG more aggressively (e.g., more finely into relatively smaller particles).
  • Movement of the counter knife 302 to reduce extension toward the front end 304 may reduce cutting aggression by the chopper 300 (e.g., to cut the MOG more coarsely into relatively larger particles).
  • the control system 120 may be communicatively coupled to a counter knife actuator 306 and may output a control signal to instruct the counter knife actuator 306 to adjust the position of the counter knife 302.
  • the control system 120 may output the control signal based on sensor data indicative of a size of discharged MOG and/or detected congestion of the MOG in the row unit 204.
  • the counter knife may have a different configuration (e.g., the counter knife may have a different geometry, such as a triangular shape), the counter knife may be moved in a different manner (e.g., translated toward or away from the front end 304), or the counter knife may be omitted.
  • the header 200 further includes one more anti-wrap knives 308.
  • the anti-wrap knife/knives 308 may block entanglement of the MOG around the feed rollers 260.
  • a respective anti-wrap knife 308 may be positioned laterally adjacent to each feed roller 260. A portion of the MOG may remain in engagement with one of the feed rollers 260 during rotation of the feed roller 260, such that the MOG is at least partially wrapped about the feed roller 260, potentially bypassing the chopper 300.
  • the anti-wrap knife 308 adjacent to the feed roller 260 may cut the MOG to block continued movement of the MOG about the feed roller 260, thereby enabling discharge of the MOG from the header 200. That is, rotation of the feed roller 260 may drive the MOG toward the anti-wrap knife 308, which may cut the MOG and block the MOG from further entangling about the feed roller 260.
  • the anti-wrap knife 308 may be positioned with respect to the feed roller 260 to provide clearance between the feed roller 260 and the anti-wrap knife 308 while enabling the anti-wrap knife 308 to cut the MOG into sufficiently fine particles. For example, too much clearance between the feed roller 260 and the anti-wrap knife 308 may not enable the anti-wrap knife 308 to cut smaller sized MOG. Thus, presence of larger sized MOG (e.g., the MOG that was not cut by the anti-wrap knife 308 or the chopper 300 before discharge) on the field may indicate excessive clearance between the feed roller 260 and the anti-wrap knife 308, even though the chopper 300 may be operating as desired.
  • MOG e.g., the MOG that was not cut by the anti-wrap knife 308 or the chopper 300 before discharge
  • the size of the MOG detected by the sensor(s) 126 may indicate the clearance between the feed roller 260 and the anti-wrap knife 308 is undesirable (e.g., above a threshold value).
  • detection of discharged MOG having a size above a threshold size while the chopper 300 is operating at above a threshold speed may indicate that the clearance between the anti-wrap knife 308 and the adjacent feed roller 260 is above a threshold value.
  • the control system 120 may output a notification to inform a user to inspect positioning of the anti-wrap knife 308. Additionally or alternatively, the control system may adjust an operation of the header and/or of the agricultural system, such as to automatically adjust a positioning of the anti-wrap knife with respect to the feed roller via an anti-wrap knife actuator 310.
  • FIG. 5 is a view of an embodiment of an interface 330 that may be utilized to adjust operation of the agricultural system of FIG. 1 .
  • the interface 330 may be accessible to a user of the agricultural system.
  • the interface 330 may be disposed within the cab of the agricultural system in which the user may be positioned.
  • the interface 330 may include a display (e.g., a touchscreen) in some embodiments.
  • the interface may include additional/different component(s), such as mechanical device(s) (e.g., button(s), switch(es), knob(s)).
  • the interface 330 may be communicatively coupled to the control system of the agricultural system.
  • operations of different components of the header may be adjusted to achieve different target operating parameter values, such as within a target range of values. For example, increasing the speed of the chopper may cut the MOG more finely to reduce the size of the MOG particles, but may utilize more power and therefore increase consumption of resources. Indeed, adjusting operation of a component may adjust a value of a first operating parameter toward a corresponding target value (e.g., reduce size of the MOG particles) and also change a value of a second operating parameter (e.g., increase resource consumption). Thus, operations may be controlled based on a desirable performance of the agricultural system to achieve a particular target operating parameter value.
  • the agricultural system may be operated in different operating modes (e.g., agricultural modes) associated with achieving different target operating parameter values.
  • operating modes may be selected by an interaction between a user and the interface 330, such as via tactile input provided by the user.
  • the control system may receive the user input, determine the operating mode selected by the user based on the user input, and adjust the operation of the agricultural mode based on the operating mode.

Additional or alternative operating modes may also be presented by the interface.
  • each icon 334, 336, 338, 340 may be associated with corresponding, respective operational adjustments of the agricultural system to adjust an operating parameter toward a target value, and selection of one of the icons 334, 336, 338, 340 may cause the control system to adjust the operation of the agricultural system in accordance with the operating mode of the selected icon.
  • Selection of the first icon 334 may cause the control system to control the agricultural system to increase the rate at which crops are harvested and processed (e.g., to remove crop from soil, to separate desirable crop material from the MOG, to discharge the MOG).
  • the control system may output one or more control signals to increase speed of the feed rollers to increase a rate at which crop is removed from soil and is moved through the header to separate desirable crop material and the MOG.
  • the control signal(s) may also increase speed of the chains to deliver the desirable crop material to the conveyors more quickly, increase speed of the conveyors to deliver the desirable crop material into the agricultural crop processing system more quickly, increase travel speed of the agricultural system to engage and gather the crops more quickly, increase operation of the agricultural crop processing system (e.g., the thresher) to process crops more quickly, or a combination thereof.
  • Selection of the second icon 336 may cause the control system to control the agricultural system to cut the MOG into smaller particles. That is, the agricultural system may further reduce the size of the MOG being discharged upon selection of the second icon 336.
  • the control system may output one or more signals to increase the speed of the chopper to cut the MOG more finely, adjust positioning of the counter knife to enable the chopper to cut the MOG into smaller particles, or a combination thereof.
  • Selection of the third icon 338 may cause the control system to control the agricultural system to reduce loss of desirable crop material caused by impact between the crop and the deck plates.
  • the control system may output one or more control signals to reduce a speed of the feed rollers to reduce a speed at which the crop impacts the deck plates.
  • Selection of the fourth icon 340 may cause the control system to control the agricultural system to reduce power usage and resource consumption.
  • the control system may output one or more control signals that reduce the speed of various components, such as to reduce a speed of the feed rollers, to reduce a speed of the chopper, to reduce the travel speed, to reduce the speed of the chain, to reduce the speed of the conveyors, or a combination thereof.
  • the control signal(s) may also adjust operation of other components to reduce power usage, such as to reduce operation of the thresher, of the cleaning system, of the MOG spreading system, of any other component(s) that may consume resources to operate, or a combination thereof.
  • selection of the icons 334, 336, 338, 340 may cause the control system to adjust operation of the agricultural system incrementally or gradually.
  • a single selection of the first icon 334 may cause the control system to adjust operation of a component of the agricultural system by a fixed amount (e.g., to increase operation by a fixed speed), such as to increase the rate at which the agricultural system harvests crops
  • an additional selection of the first icon 334 may cause the control system to adjust operation of the component by an additional fixed amount, such as to further increase the rate at which the agricultural system harvests crops.
  • the icons 334, 336, 338, 340 may be selected by the user to adjust operation of the agricultural system iteratively, progressively, or finely for increased control.
  • the fixed amount may be an amount established or adjusted based on a user input, based on sensor data (e.g., a characteristic of the MOG), or both.
  • an icon may be associated with an operating setting of a component of the agricultural system, and selection of the icon may cause the control system to adjust operation of the component toward the operating setting (e.g., regardless of a current operating setting of the component). In such embodiments, an additional selection of the icon while the component is at the operating setting may not further adjust the operation of the component.
  • Multiple operating modes may also be selected by the user to adjust operation of the agricultural system.
  • selection of the fourth icon 340 may reduce a speed of operation of various components of the agricultural system to reduce power usage.
  • selection of the third icon 338 may further reduce a speed of operation of the feed rollers while maintaining the reduced speed of operation of other components associated with reduced power usage. In this way, the adjusted operation of the agricultural system may enable multiple target operating parameter values to be achieved.
  • the interface 330 also includes multiple windows that display information to a user.
  • a first window 342 may textually display various operating parameter information, such as the speed of the chopper, the power usage, the speed of the feed rollers, the travel speed, the speed of the conveyors, the position of the counter knife, another suitable operating parameter, or any combination thereof.

  • the user may determine that the power usage is excessive and, in response, may select the fourth icon 340 to reduce the power usage by the agricultural system.
  • the user may determine that the power usage is not sufficiently reduced upon selection of the fourth icon 340, and the user may inspect operation of the agricultural system to determine the cause of the continued excessive power usage, such as to determine whether there is a congestion or a blockage.
  • the operating parameters may be presented in another manner.
  • the interface may present a video feed of the operation of the components, of the crop material processed by the agricultural system, of the MOG discharged and distributed on the field, or a combination thereof.
